Care
Light
Place Hamelia patens in full sun to get generous flowering and intense flower color. Partial shade is tolerated in very hot regions. A minimum of 6 to 8 hours of direct sunlight daily is needed.
Watering
Water regularly without letting the soil dry out completely, especially during the growth and flowering period. Reduce watering in winter or in temperate climates. Prefer well-drained soil to prevent root rot.
Soil
Hamelia prefers rich, light and well-structured soil, slightly acidic to neutral. Adding potting soil or organic matter improves fertility. Make sure there is good drainage to prevent rot.
Fertilizing
Apply balanced fertilizer or one slightly rich in potassium and phosphorus during growth and flowering (spring-autumn), every 3 to 4 weeks. Reduce applications in winter or adjust according to your region's conditions.
Pruning and maintenance
Prune lightly after flowering or in late winter to maintain a compact shape and encourage branching. Remove dead or weak branches. Annual pruning rejuvenates the shrub and stimulates better flowering.
Diseases and pests
Hamelia patens can be affected by whiteflies and mealybugs, especially under cover. Watch for signs of rot in case of excess humidity. Good air circulation and moderate watering significantly reduce these risks.
Did you know?
Hamelia patens is a plant prized by butterflies and hummingbirds that delight in its abundant nectar, making it a true source of life in tropical and subtropical gardens. Its nickname 'Firebush' comes from the flaming hue of its flowers, which glow red at dusk and attract nocturnal pollinators.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
